Estimating solar array power generation

ABSTRACT

In an approach for estimating solar array power generation for an installation of a solar array, a processor determines a location of an installation of a solar array. A processor determines, over a course of a specified time interval, a path of traversal of a source of energy relative to the location of the installation of the solar array. A processor scans an area surrounding the solar array. A processor estimates, based, at least in part, on the path of traversal of the source of energy and the area surrounding the solar array, an amount of power to be generated by the solar array.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of solar power technology, and more particularly to determining an amount of sunlight received by a solar array over a time interval in order to estimate how much power is generated by the solar array.

A solar array is a power system designed to supply usable solar power by means of photovoltaics. A solar array consists of an arrangement of several components, including multiple solar panels to absorb and directly convert sunlight into electricity, a solar inverter to change the electrical current from direct current (DC) to alternating current (AC), as well as mounting, cabling, and other accessories to set up a working system. A solar array encompasses the ensemble of solar panels, the visible part of the photovoltaic system, and does not include the other hardware that is often summarized as the balance of system.

Solar panel refers to a photovoltaic module, solar hot water panel, or set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A photovoltaic module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. A single solar module can produce a limited amount of power; most installations include multiple modules.

Sunlight is a portion of the electromagnetic radiation given off by the sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is filtered through the Earth's atmosphere, as daylight is when the sun is above the horizon. When direct solar radiation is not blocked by clouds, there is an experience of sunshine, a combination of bright light and radiant heat. When the direct solar radiation is blocked by the clouds or reflects off other entities, there is an experience of diffused light. The cumulative time during which an area receives direct irradiance from the sun of at least 120 watts per square meter is called sunshine duration.

A global positioning system (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. GPS provides critical capabilities to military, civil, and commercial users around the world. GPS is maintained by the United States government and is freely accessible to anyone with a GPS receiver.

DETAILED DESCRIPTION

With the current state of solar power technology, solar array technology advances and electric cars with solar arrays have become more prevalent. The amount of sun that a car is exposed to throughout the day has an effect on the length of time the vehicle can be used before the need to use a charging station.

Embodiments of the present invention recognize the need for a user to be assured that the user's object, which includes solar panels, whether the solar panels are on a vehicle or house, will be charged enough to be able to satisfy the user's needs throughout a day or night. A user could have a variety of needs, depending on whether the object is mobile or stationary. For example, if the object is mobile, the user's needs may include a vehicle having enough power to return home after work without stopping by a charging station. On the other hand, if the object is stationary, the user's needs may include having enough power to host a party that would require more power than a typical day. Embodiments of the present invention detail a program that can be used to identify how much sunlight the solar array will receive over an interval of time, and therefore, how much power the solar array might generate.

Embodiments of the present invention will now be described in detail with reference to the Figures.

FIG. 1 depicts a block diagram of computing system 10, in accordance with one embodiment of the present invention. FIG. 1 provides an illustration of one embodiment and does not imply any limitations with regard to the environments in which different embodiments may be implemented.

In the depicted embodiment, computing system 10 includes server 30 and computing device 40 interconnected over network 20. Network 20 may be a local area network (LAN), a wide area network (WAN) such as the Internet, a cellular data network, any combination thereof, or any combination of connections and protocols that will support communications between server 30 and computing device 40, in accordance with embodiments of the invention. Network 20 may include wired, wireless, or fiber optic connections. Computing system 10 may include additional computing devices, servers, or other devices not shown.

Server 30 may be a management server, a web server, or any other electronic device or computing system capable of processing program instructions and receiving and sending data. In some embodiments, server 30 may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, or any programmable electronic device capable of communicating with computing device 40 via network 20. In other embodiments, server 30 may represent a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In another embodiment, server 30 represents a computing system utilizing clustered computers and components to act as a single pool of seamless resources. In the depicted embodiment, server 30 contains generic program 130 and generic database 140. In other embodiments, server 30 may include generic program 130, generic database 140, and/or other components, as depicted and described in further detail with respect to FIG. 4.

Computing device 40 may be a desktop computer, laptop computer, netbook computer, or tablet computer. In general, computing device 40 may be any electronic device or computing system capable of processing program instructions, sending and receiving data, and communicating with server 30 via network 20. In the depicted embodiment, computing device 40 contains solar array program 110 and solar array database 120. In other embodiments, computing device 40 may include solar array program 110, solar array database 120, and/or other components, as depicted and described in further detail with respect to FIG. 4.

Solar array program 110 estimates solar array power generation for objects throughout the course of a specified time interval. In doing so, solar array program 110 receives an indication of start-up and/or stoppage of an object (e.g., automobile or boat) that holds the installation of the solar array. Throughout the application, holding the installation of the solar array means that the solar array is installed on top of, under, inside, or, otherwise, attached to the object. Solar array program 110 determines a path of traversal of a source of energy relative to the location of the installation of the solar array. Solar array program 110 scans the area surrounding the solar array. Solar array program 110 estimates the power generation and notifies a user. In the depicted embodiment, solar array program 110 resides on computing device 40. In other embodiments, solar array program 110 may reside on another computing device, server, or server 30, provided that solar array program 110 can access solar array database 120, generic program 130, and generic database 140 via network 20.

Solar array database 120 may be a repository that may be written to and/or read by solar array program 110. In some embodiments, a program (not shown) may allow an administrator or other user to define various maps and GPS coordinates and store to solar array database 120. In other embodiments, solar array database 120 may store already determined paths or estimations of power. For example, if a user parks in the same location for work every day, solar array program 110 can determine power estimation during each season for a typical work day and store that information to solar array database 120. In the depicted embodiment, solar array database 120 resides on computing device 40. In other embodiments, solar array database 120 may reside on another computing device, server, or server 30, provided that solar array database 120 is accessible to solar array program 110 via network 20.

Generic program 130 may be any program on server 30 that may be accessed by solar array program 110 over network 20. For example, generic program 130 may be an application or program that is designed to obtain information concerning various weather activities and seasonal information, such as sunrise and/or sunset times. Solar array program 110 may use current information gathered by generic program 130 to obtain precise, current or future weather pattern information.

Generic database 140 may be any database on server 30 that may be accessed by solar array program 110 over network 20. For example, generic database 140 may be a repository that stores prior or current weather pattern information obtained by a program or application. Solar array program 110 may use archived information stored to generic database 140 to obtain historical weather pattern information.

FIG. 2 depicts a flowchart of the steps of a solar array program, executing within the computing system of FIG. 1, in accordance with an embodiment of the present invention. Solar array program 110 estimates solar array power generation for objects throughout the course of a specified time interval.

In step 210, solar array program 110 receives indication of start-up of an object (e.g., automobile or boat) that holds the installation of the solar array. In some embodiments, solar array program 110 receives an indication of start-up from starting the ignition of an automobile, boat, or other type of vehicle. In other embodiments, solar array program 110 receives an indication of start-up from the push of a button, or any other type of switch that could be used to alert a program related to the installation of the solar array to begin. The button, or switch, could also be used for a stationary solar array. Although the button, or switch, would be more prevalent on a stationary solar array, the button, or switch, could also be used for a moving solar array. The button, or switch, would allow the driver of a vehicle to choose a starting and stopping point that is different from the starting and stopping of the vehicle's ignition. Still, in some embodiments, solar array program 110 does not receive an indication of start-up and runs continuously.

In step 220, solar array program 110 receives indication of stoppage of an object (e.g., automobile or boat) that holds the installation of the solar array. In one embodiment, solar array program 110 receives an indication of stoppage from turning off the ignition of an automobile, boat, or other type of vehicle. In other embodiments, solar array program 110 receives an indication of stoppage from the push of a button, or any other type of switch that could be used to alert an object that holds the installation of the solar array to stop. The button, or switch, could be used on a stationary solar array. Although the button, or switch, would be more prevalent on a stationary solar array, the button, or switch, could also be used in a moving solar array. The button, or switch, would allow the driver of a vehicle to choose a starting and stopping point that is different from the starting and stopping of the vehicle's ignition.

In some embodiments, solar array program 110 may continue without receiving an indication of stoppage of an object (e.g., automobile or boat) that holds the installation of the solar array program related to the installation of the solar array. In such an embodiment, a user may input a location where the user wishes to park, and solar array program 110 plots the relative position of the sun over an interval of time at the specified location.

In step 230, solar array program 110 determines, over a course of a specified time interval (e.g., three hours, eight hours, all day), a path of traversal of a source of energy relative to the location of the installation of the solar array.

In one embodiment, the specified time interval is given by the user. For example, the user may only want information during the user's workday. In other embodiments, the specified time interval is determined by solar array program 110, based on prior user needs. For example, solar array program 110 may use the information stored to solar array database 120 for particular days of the week to provide a time interval that suits the user's needs.

In one embodiment, solar array program 110 retrieves an already plotted path of traversal from solar array database 120 or generic database 140. For example, on a certain day in a certain time zone, there may be information about the path of the sun for various types of locations (e.g., cities, farms, etc.). In other embodiments, solar array program 110 uses sensors, such as a global positioning system (GPS) or a compass, to plot the path of traversal. For example, solar array program 110 may use a range finder type sensor to follow the path of the sun over the specified time interval. Whenever the range finder returns a value that is not infinite, there is an obstructing entity between the solar array and the path of the sun, indicating, for example, shadows on the solar array. In one embodiment, solar array program 110 uses a single sensor device that rotates. In other embodiments, solar array program 110 uses multiple sensor devices that can be correlated or synced.

In one embodiment, the sensors are located on or near the installation of the solar array. In other embodiments, the sensors are not located on or near the installation of the solar array, but instead are located on a building or other structure near the installation of the solar array, such that solar array program 110 may retrieve the information from other locations.

In step 240, solar array program 110 scans an area surrounding the solar array. In one embodiment, solar array program 110 retrieves a map of one or more entities in existence between the installation of the solar array and the path of traversal of the source of energy over the course of the specified time interval from solar array database 120 or generic database 140. For example, the map may have been previously used by another user from a certain day in the same area that relates to the entities in the area surrounding the current user's solar array. In other embodiments, solar array program 110 creates a map of entities that exist between the solar array and the path of the sun throughout the course of the specified time interval. For example, the entities could be stationary (e.g., building or house) or could move (e.g., food truck) throughout the course of the specified time period. Solar array program 110 uses the map to identify time intervals and particular times when the solar array is in the shadow of the entities (i.e., at least partially blocked) that exist between the solar array and the path of the sun, assuming no cloud coverage or other events unaffected by vehicle placement, for example, a solar eclipse.

In one embodiment, solar array program 110 creates the map throughout a day while the vehicle is parked, tracking stationary entities and movement of entities that block the source of energy from the solar array, and the power estimation is performed at the end of the day. In other embodiments, solar array program 110 creates the map when the vehicle is parked, and the power estimation is done at that time. Additionally, in some embodiments, solar array program 110 identifies the type of entity that is blocking the solar array from the sun. For example, solar array program 110 may identify that the entity is a building, truck, tree, etc.

In step 250, solar array program 110 estimates power generation. In one embodiment, solar array program 110 takes into account weather patterns throughout the day to identify levels of cloud coverage. In some embodiments, solar array program 110 retrieves the weather pattern information from data previously stored to solar array database 120. In other embodiments, solar array program 110 receives the weather pattern information from generic program 130. For example, generic program 130 may be an application or program that is designed to obtain information concerning various weather activities for specified locations. Still, in some embodiments, solar array program 110 retrieves the weather pattern information from generic database 140. For example, generic database 140 may be a repository that stores prior or current weather pattern information obtained by a program or application.

The information obtained by solar array program 110, for example, weather pattern information, the path of traversal of the source of energy, and/or the map of entities, is used to estimate how much power is generated by the solar array and if that generated power would be enough to satisfy the needs of the user. In various embodiments of the present invention, solar array program 110 calculates the estimation of power generated by the solar array using known methods. In some embodiments, the user knows the amount of power needed for a particular task. For example, the user may know that it takes 30 miles to get home from work, and solar array program 110 determines how many miles the estimated power generation will carry the user. In another example, the output from solar array program 110 may be in terms of power, such as, 50 kWh (kilowatt-hour). If the user knows it takes 40 kWh to travel 30 miles, then the user knows there is enough power to travel home from work. Solar array program 110 can estimate (i.e., calculate) the power generation by any means that allow a user to determine if the amount of power generated is high enough for what the user may require. In one embodiment, the user determines if the estimated power generated is sufficient. In other embodiments, solar array program 110 determines if the estimated power generated is sufficient. In one embodiment, for example, the estimation may be based, at least in part, on the path of traversal of the source of energy and the area surrounding the solar array.

Unlike solar arrays placed on stationary objects, such as a house, solar arrays placed on a vehicle have a wide range of acceptable light exposed to the solar array. Solar array program 110 provides a way for the vehicle to identify not just how much sunlight the vehicle is currently exposed, but how much sunlight the vehicle is likely to be exposed to throughout the day, assuming the vehicle stays in its current location.

In step 260, solar array program 110 notifies a user. The information determined by solar array program 110 in step 250, for example, an estimate of power generated, is filtered back to the user, so the user can decide how to proceed. In one embodiment, solar array program 110 notifies a user of the installation of the solar array of the particular times in which the installation of the solar array is at least partially blocked from the source of energy. In some embodiments, solar array program 110 notifies the user through an audio system, such as a phone call, radio transmission, or through a navigation system's audio output. In other embodiments, solar array program 110 notifies the user through a visual system, such as a text message, email, or a message on a navigation system's display unit. In one embodiment, solar array program 110 only gives the amount of power generated. In other embodiments, solar array program gives the amount of power generated and suggests to the user whether or not the power generated is enough for the user's need. Still, in some embodiments, solar array program 110 notifies the user that a structure is blocking the source of energy from reaching the solar array and suggests that the user move the vehicle.

FIGS. 3A and 3B depict examples of objects that are partially blocked from the sun by an entity (e.g., a building), in accordance with an embodiment of the present invention.

FIG. 3A depicts mobile object 310, solar power unit 320, and obstructing structure 330. In the depicted embodiment, mobile object 310 is a car. In other embodiments, mobile object 310 could be a motorcycle, boat, or any other mobile object that uses a solar array to generate power. In the depicted embodiment, solar power unit 320 is the sun. In other embodiments, solar power unit 320 could be any other unit, occurring in nature or synthetic, that creates solar power similar to the sun that could be used by a solar array to generate power. In the depicted embodiment, obstructing structure 330 is a building. In other embodiments, obstructing structure 330 could be any other entity, such as a monument, statue, house, etc., that could cause mobile object 310 to be blocked from solar power unit 320.

As an example, in step 210 and/or 220 of FIG. 2, solar array program 110 may receive an indication of start-up and/or stoppage of an object (e.g., mobile object 310) that holds the installation of the solar array. In some embodiments, solar array program 110 receives an indication of start-up from a user starting the ignition of mobile object 310. In other embodiments, solar array program 110 receives an indication of stoppage from a user turning off the ignition of mobile object 310.

FIG. 3B depicts stationary object 340, solar power unit 320, and obstructing structure 330. In the depicted embodiment, stationary object 340 is a house. In other embodiments, stationary object 340 could be a building, factory, or any other stationary object that uses a solar array to generate power. In the depicted embodiment, solar power unit 320 and obstructing structure 330 are similar to the depiction in FIG. 3A.

As an example, in step 240 of FIG. 2, solar array program 110 may find obstructing structure 330 during the scan of the area surrounding the solar array and determine that obstructing structure 330 is a building. In some embodiments, solar array program 110 determines certain characteristics (e.g., height, width, etc.) of obstructing structure 330, which assists in the estimation of power generation in step 250.

Solar array program 110 optimizes vehicle positioning by using predictive methods. Solar array program 110 allows vehicles to take advantage of areas that might, at a current time, be in the shade, but for the majority of the day may be in the sunlight and able to generate power. Similarly, users would be able to avoid spots that at the current time are sunlit, but will not be in an hour. Additionally, solar array program 110 is not just limited to vehicles. Solar array program 110 could be used to assist with the installation of solar arrays on houses, or other stationary objects, that may be blocked from direct sunlight at some interval of time during the day.
